How to solve:

You have to install the full JDK, not only the JRE.

I had the same issue and solved by installing JDK.

Please use this link to download the latest JDK version 13.0.2.

Answer:

I didn’t need the full JDK, I just needed to make JRE work and none of the other answers provided above worked for me.
Maybe it used to work, but now (1st Jul 2018) it isn’t working. I just kept getting the error and the pop-up.

I eventually solved this issue by placing the following JAVA_HOME export in ~/.bash_profile:

export JAVA_HOME=/Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home

Hope this helps someone.
I’m running Mac OS High Sierra.

Answer:

Since it sounds like your JAVA_HOME variable is not set correctly, follow the instructions for setting that.

Setting JAVA_HOME environment variable on MAC OSX 10.9

I would imagine once you set this, it will stop complaining.

Answer:

In newer versions of OS X (especially Yosemite, EL Capitan), Apple has removed Java support for security reasons.
To fix this you have to do the following.

  1. Download Java for OS X 2015-001 from this link: https://support.apple.com/kb/dl1572?locale=en_US
  2. Mount the disk image file and install Java 6 runtime for OS X.

    After this you should not be seeing any of the below messages:

    – Unable to find any JVMs matching version “(null)”

    – No Java runtime present, try –request to install.

    This should resolve the issue for the pop-up shown below:

Answer:

If you came across the error when tried to generate a jks file (keystore), so try adding

/Applications/Android\ Studio.app/Contents/jre/jdk/Contents/Home/bin/keytool

before running the command, like so:

/Applications/Android\ Studio.app/Contents/jre/jdk/Contents/Home/bin/keytool -genkey -v -keystore ~/key.jks -keyalg RSA -keysize 2048 -validity 10000 -alias key
